During the Fursuit Robbers Cave Hike a pair of black vultures shown up to see if one of us Fursuiters will pass out and become their next meal. Fortunately non of us passed out and died there and they had to go hungry. They thought they had a good bet that one of us would become they next meal but that didn't happen.

From my observing these 2 I figure they are a mated pair even though these birds can be seen in large groups.
